The discussion revolves around calculating the initial upward acceleration of a 2.0x104 kg rocket with a thrust of 2.7x105 N. The correct initial acceleration can be determined using Newton's second law, resulting in an acceleration of 13.5 m/s2. Additionally, at an altitude of 5000 m, the rocket's acceleration of 6.0 m/s2 indicates that a certain mass of fuel has been burned, which can be calculated using the thrust and the change in acceleration.
PREREQUISITESAerospace engineers, physics students, and anyone involved in rocket design and performance analysis will benefit from this discussion.
Please explain how you arrived at those solutions.Cb8 said:Homework Statement:: A 2.0x104 kg rocket has a rocket motor that
generates 2.7×105 N of thrust.
A) What is the rocket's initial upward acceleration in m/s^2.
B) At an altitude of 5000 m the rocket's acceleration has
increased to 6.0 m/s?. What mass of fuel has it
burned in kg.
Relevant Equations:: 2.0x10^4 kg Rocket
2.7x10^5 N of thrust
I tried A with the solution of 9.73 and 8.69 both wrong.
